Why Share Business Broadband
Even smaller businesses can have high performance dedicated Internet
access by splitting the cost of a T1, T3 or fiber optic line with
other businesses in their building or business park. By pooling
resources, the group can afford a higher bandwidth than any individual
When to Use Pseudowires
A pseudowire is a virtual "circuit" that emulates a
traditional digital telecom service but on a packet switched network.
MPLS networks are especially suitable for pseudowires. By using
a pseudowire circuit, you can get the point to point connectivity
you desire without having to re-engineer your facilities to accommodate
a different protocol network.
Applications Demanding DS3
DS3 transport is often used for real time video transport, high
resolution images, large engineering files, and data backups to
remote data centers. You can get this bandwidth through fiber
optic delivery or over copper coaxial lines, called T3 lines.
How DS3 Relates to OC3
DS3 is a digital signal level originally developed to support
the copper based T-Carrier digital telephone trunking system.
DS3 offers about 45 Mbps of bandwidth . OC3 is a SONET optical
carrier standard running at about 155 Mbps. An OC3 link can transport
up to 3 separate DS3 services.
What is Fractional DS3 Service?
Fractional DS3, as the name implies, is a fraction of the full
DS3 bandwidth of 45 Mbps. Companies order fractional DS3 when
they don't need or want to pay for the full bandwidth offered
by DS3. Even with fractional DS3, you still need the full coaxial
or optical hardware support for 45 Mbps signaling. At low fractional
requirements, bonded T1 lines offer a more cost effective solution.
